BACKGROUND OF THE INVENTION

The present invention relates to carboalkoxy alkyl norbornanes having the generic formula: ##STR2## wherein the dashed line represents either a carbon-carbon single bond or a carbon-carbon double bond; R₁, R₂, R₃, R₄, R₆ and R₇ represents hydrogen or methyl; with the proviso that one of R₁, R₂, R₆ and R₇ is methyl and each of the other of R₁, R₂, R₆ and R₇ is hydrogen; and with the further proviso that R₃ and R₄ are not both methyl, produced by the novel process of our invention, and to novel compositions using one or more of such norbornane derivatives to alter, modify or enhance the flavor and/or aroma of consumable materials or impart flavor and/or aroma to consumable materials.

There has been considerable work performed relating to substances which can be used to impart (modify, augment or enhance) flavors and fragrances to (or in) various consumable materials. These substances are used to diminish the use of natural material, some of which may be in short supply, and to provide more uniform properties in the finished product.

Fruity, burnt fruit-like, raspberry, sweet, seedy, berry-like, red berry-like, blueberry-like, spicy, black pepper-like, herbaceous, clove-like, vermouth-like, strawberry-like, wild strawberry-like, camphoraceous and balsamic aromas with fruity burnt fruit-like, raspberry, seedy, sweet, berry-like, red berry-like, blueberry-like, spicy, black pepper-like, herbaceous, clove-like, vermouth-like, strawberry-like, wild strawberry-like, camphoraceous, balsamic and bitter tastes are particularly desirable for many uses in foodstuff flavors, chewing gum flavors, toothpaste flavors and medicinal product flavors.

Spicy, cooling, clove-like, cinnamon bark-like, sweet, fruity, berry-like, juicyfruit, woody, piney, blueberry, banana, green, herbaceous, strawberry-like and dill aroma and taste characteristics both prior to and on smoking in the mainstream and in the side stream.

Intense and pleasant fruity, strawberry-like, raspberry, Reseda body-like, banana-like, creamy, camphoraceous, herbaceous, sweet, spicy, woody, eucalyptol-like, rum/butterscotch-like, balsamic, green, minty, borneol-like and "medicinal" aromas with strong camphor, minty and calamnus-like undertones are desirable in several types of perfume compositions, perfumed articles and colognes.

Arctander, "Perfume and Flavor Chemicals", 1969, Volume I discloses the use in perfume compositions and in foodstuff flavors of camphene carbinyl acetate thus:

"1029: 2,2-Dimethyl-Delta-2-beta-norbornane-2-ethylacetate" "Camphene carbinyl acetate". ##STR3## Mild and sweet-woody odor with a floral-piney undertone. The commercial products are probably not well defined single chemicals, and great variations in odor have been observed.

This ester has been developed in line with the research on Sandalwood type odors. The parent alcohol "Camphene carbinol" was once considered useful as a Sandalwood type material, but it has found more use as a sweetening and enriching ingredient in sophisticated Pine fragrances. The title ester finds limited use in perfume compositions of woody character, Fougeres, Pine fragrances, etc. and it blends very well with the Cyclohexanol derivatives, Ionones, iso-Bornylacetate, Nitromusks, etc."

Mellor and Webb, J. Chem. Soc. Perkin Trans II, 1974 (I) 26-31 discloses production of the compounds having the structures: ##STR4## together with several other methyl substituted isomers thereof in admixture, according to the reaction: ##STR5## The Mellor and Webb article however, does not disclose the reaction to take place at low temperatures in the presence of an alkyl aluminum halide or dialkyl aluminum halide whereby but two isomers are produced in a controlled fashion in high yields thus yielding an organoleptically acceptable mixture of carboalkoxy norbornane derivatives.

Thus, nothing in the prior art indicates production for organoleptic uses of compounds having the generic structure: ##STR6## wherein the dashed line represents a carbon-carbon single bond or a carbon-carbon double bond and R₁, R₂, R₃, R₄, R₅, R₆ and R₇ are as defined above.

U.S. Pat. No. 4,143,074 discloses, generically, compounds which are esters and contain the norbornyl moiety having the structures: ##STR7## wherein either or both of R₁ or R₂ is hydrogen or lower alkyl, R₃ is hydrogen or lower alkyl and n is zero or 1 and in addition, the compound having the structure: ##STR8## wherein R₆ is alkyl having from one up to eight carbon atoms.

THE INVENTION

It has now been discovered that novel solid and liquid foodstuff, chewing gum, medicinal product and toothpaste compositions and flavoring compositions therefor having the fruity, burnt fruit, raspberry, seedy, sweet, berry-like, red berry-like, blueberry-like, spicy, black pepper-like, herbaceous, clove-like, vermouth-like, strawberry-like, wild strawberry-like, camphoraceous and balsamic aroma characteristics and flavor characteristics as well as bitter taste characteristics; as well as novel smoking tobacco and smoking tobacco flavoring compositions having spicy, cooling, clove-like, cinnamon bark-like, sweet, fruity, berry-like, juicyfruit, woody, piney, blueberry, banana, green, herbaceous, strawberry-like and dill aroma and taste prior to and on smoking in both the mainstream and the sidestream; as well as novel perfume compositions, colognes and perfumed articles (e.g., solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softeners and dryer-added fabric softener articles) having intense and long lasting fruity, banana, creamy, camphoraceous, strawberry-like, raspberry, reseda body-like, herbaceous, sweet, spicy, woody, eucalyptol-like, rum/butterscotch-like, balsamic, green, minty, borneol-like, and medicinal aromas with strong camphor, minty and calamnus-like undertones may be provided by utilization of one or more of the substituted norbornane derivatives having the generic structure: ##STR75## wherein the dashed line represents either a carbon-carbon single bond or a carbon-carbon double bond and R₁, R₂, R₃, R₄, R₆ and R₇ represent either hydrogen or methyl with the proviso that one of R₁, R₂, R₆ and R₇ is methyl and each of the other of R₁, R₂, R₆ and R₇ is hydrogen; and with the further proviso that R₃ and R₄ are not both methyl, in foodstuffs, chewing gums, toothpastes, medicinal products, perfume compositions, perfumed articles, colognes and smoking tobaccos as well as smoking tobacco substitutes.

Unless otherwise specified, representations herein are intended to indicate "cis" isomers, "trans" isomers, mixtures of "cis" and "trans" isomers and "endo" isomers and "exo" isomers with respect to the norbornane ring moiety and dextro and levorotatory isomers as well as racemic mixtures of optical isomers of the norbornane derivatives of our invention.

Thus, the generic structure: ##STR76## is intended to mean both "endo" and "exo" isomers having the structures: ##STR77##

The novel substituted norbornane derivatives of our invention useful as indicated supra may be produced by reacting a 1-methylcyclopentadiene or 2-methylcyclopentadiene having one of the structures: ##STR78## or a mixture of these methylcyclopentadienes defined according to the generic structure: ##STR79## with an alkyl acrylate derivative defined according to the generic structure: ##STR80## in the presence of a specific Lewis acid catalyst at relatively low temperatures (e.g., 0°-50° C.) or in the absence of a catalyst at relatively high temperatures (e.g., 170°-250° C.).

When using the catalytic process of our invention, an isomer mix will be produced which contains isomers in proportions and (in some cases) having structures different from the proportions and (in some cases) structures produced using the high temperature reaction of our invention (which reaction is carried out in the absence of catalyst).

The reactant having the structure: ##STR81## represents a "cis" isomer or a "trans" isomer or a mixture of "cis" and "trans" isomers. Thus, the "trans" isomer may be represented by the structure: ##STR82## and the "cis" isomer may be represented by the structure: ##STR83##

When performing the process for preparing compounds useful in the practice of our invention where the use of a catalyst is required, the catalyst for the reaction may be an alkyl aluminum dihalide or a dialkyl aluminum halide for example RAlCl₂ or R₂ AlCl wherein R represents methyl, ethyl or n-propyl or i-propyl. The preferred caralyst is ethyl aluminum dichloride. Other Lewis acids such as aluminum trichloride, stannic chloride, zinc chloride, ferric chloride and titanium tetrachloride have been attempted to be used but such attempts have proved to be unsuccessful with minimal or no yields of product being produced. The temperature range of the reaction may vary from about 0° C. up to about 50° C. with ambient temperatures, from 20° up to 30° C. being preferred. The reaction pressure will not affect the yield but conveniently and economically, a reaction pressure of atmospheric is preferred. Thus, the catalyst for the reaction may be defined according to the formula: R_(m) ' AlCl_(n) wherein R' is C₁ -C₃ alkyl and the sum, m+n, equals 3; with m being one or two and n being one to two.

The reaction mass resulting from the catalytic process is a mixture of compounds containing unsaturation in the norbornane moieties defined according to the generic structures: ##STR84##

When performing the reaction for preparing compounds useful in the practice of our invention in the absence of catalysts (that is where no catalyst is required), the reaction temperature is in the range of from about 170° C. up to about 250° C. with a temperature of 200° C. being preferred. When the reaction is carried out at such high temperatures, the reaction is carried out under pressures greater than atmospheric in a closed pressurized system. The pressure of reaction may vary from about 10 psig up to about 100 psig depending on the vapor pressure of the reaction mass and depending upon the temperature at which it is desired to carry out the reaction. Thus, reaction pressures of between 10 psig and 100 psig will not in and of themselves affect the yield of product although too high a temperature of reaction will affect the yield of product in view of the higher degree of decomposition and too low a reaction temperature will affect the yield of product in that the reaction will take an inordinately long perod of time in order to achieve a given yield. Thus, it appears that the optimum reaction temperature in the absence of catalyst is 200° C. Reaction temperatures below 170° C. will not be high enough to effect the initiating decomposition of the dimethyl dicyclopentadiene starting material which it is most practical to use as a precursor of the dimethyl dicyclopentadiene.

The reaction mass resulting from the "thermal-non-catalytic" process is also a mixture of compounds containing unsaturation in the norbornane moiety defined according to the generic structures: ##STR85## wherein R₃, R₄ and R₅ are as defined above.

The above unsaturated compounds may be used "as is" for their individual organoleptic properties or mixtures of compounds may be used "as is" for their organoleptic properties or the compounds individually or in admixture may be further hydrogenated using hydrogen gas at super atmospheric pressures. When it is desired to use the compounds "as is" for their organoleptic properties, it is preferable to refine the reaction mass as by fractional distillation or high pressure liquid chromatography thereby creating one or more products usable as set forth above.

When it is desired to carry out a hydrogenation, the hydrogenation is carried out preferably on mixtures of products containing compounds having unsaturation prepared by the above named Diels-alder reactions. Thus, when carrying out the hydrogenation on a mixture of products containing compounds resulting from the catalytic process and having the structures: ##STR86## wherein R₃, R₄ and R₅ are defined as above, compounds having the structures: ##STR87## will be produced.

When carrying out the hydrogenation on a mixture of products containing the compounds resulting from the non-catalytic, thermal process and having the structures: ##STR88## the compounds having the structures: ##STR89## will be produced.

In either case, it is preferable to carry out the hydrogenation at pressures of from about 20 psig up to about 2,000 psig with a pressure range of from about 40 up to about 80 psig being preferred. It is also preferable for the reaction to be carried out in the presence of a catalyst such as Raney Nickel, palladium on carbon, palladium on calcium carbonate, palladium on barium surfate and platinum. When using the palladium-salt catalyst, it is preferred to use from about 3% up to about 12% palladium on salt, for example 5% palladium on calcium carbonate.

Thus, the reaction sequence which is embodied within our invention when using the catalytic procedure may be illustrated as follows: ##STR90## wherein one of R₃ or R₄ is hydrogen and the other of R₃ or R₄ is methyl; wherein R₅ represents C₁ -C₄ lower alkyl; wherein R' represents C₁ -C₃ alkyl; and wherein M+N equals three with M being equal to one or two and N being equal to one or two.

Furthermore, the reaction sequence which is embodied within our invention when using the high temperature non-catalytic thermal Diels-alder reaction may be illustrated as follows: ##STR91## wherein R₁, R₂, R₃, R₄, R₅, R₆ and R₇ are as defined above.

The following tables set forth the products covered by our invention and the alkyl acrylate precursor reactant starting materials to be reacted with the methylcyclopentadienes to produce said products and in addition sets forth the organoleptic properties of the products of our invention:

When the norbornane derivatives of our invention are used as food flavor adjuvants, the nature of the co-ingredients included with each of the said norbornane derivatives in formulating the product composition will also serve to alter, modify, augment or enhance the organoleptic characteristics of the ultimate foodstuff treated therewith.

As used herein in regard to flavors, the terms "alter", "modify" and "augment" in their various forms mean "supplying or imparting flavor character or note to otherwise bland, relatively tasteless substances or augmenting the existing flavor characteristic where a natural flavor is deficient in some regard or supplementing the existing flavor impression to modify its quality, character or "taste".

The term "enhance" is used herein to mean the intensification of a flavor or aroma characteristic or note without the modification of the quality thereof. Thus, "enhancement" of a flavor or aroma means that the enhancement agent does not add any additional flavor note.

As used herein, the term "foodstuff" includes both solid and liquid ingestible materials which usually to, but need not, have nutritional value. Thus, foodstuffs include soups, convenience foods, beverages, dairy products, candies, vegetables, cereals, soft drinks, snacks and the like.

As used herein, the term "medicinal product" includes both solids and liquids which are ingestible non-toxic materials which have medicinal value such as cough syrups, cough drops, aspirin and chewable medicinal tablets.

The term "chewing gum" is intended to mean a composition which comprises a substantially water-insoluble, chewable plastic gum base such as chicle, or substitutes therefor, including jelutong, guttakay, rubber or certain comestible natural or synthetic resins or waxes. Incorporated with the gum base in admixture therewith may be plasticizers of softening agents, e.g., glycerine; and a flavor compostion which incorporates one of more of the norbornane derivatives of our invention, and in addition, sweetening agents which may be sugars, including sucrose or dextrose and/or artificial sweeteners such as cyclamates or saccharin. Other optional ingredients may also be present.

Substances suitable for use herein as co-ingredients or flavoring adjuvants are well known in the art for such use, being extensively described in the relevant literature. It is a requirement that any such material be "ingestibly" acceptable and thus non-toxic and otherwise non-deleterious particularly from an organoleptic standpoint whereby the ultimate flavor and/or aroma of the consumable material used is not caused to have unacceptable aroma and taste nuances. Such materials may in general be characterized as flavoring adjuvants or vehicles comprising broadly stabilizers, thickeners, surface active agents, conditioners, other flavorants and flavor intensifiers.

Stabilizer compounds include preservatives, e.g., sodium chloride; antioxidants, e.g., calcium and sodium ascorbate, ascorbic acid, butylated hydroxyanisole (mixture of 2- and 3-tertiary-butyl-4-hydroxyanisole), butylated hydroxytoluene (2,6-di-tertiary-butyl-4-methylphenol), propyl gallate and the like and sequestrants, e.g., citric acid.

Thickener compounds include carriers, binders, protective colloids, suspending agents, emulsifiers and the like, e.g., agar agar, carrageenan; cellulose and cellulose derivatives such as carboxymethyl cellulose and methyl cellulose; natural and synthetic gums such as gum arabic, gum tragacanth; gelatin, proteinaceous materials; lipids; carbohydrates; starches, pectins and emulsifiers, e.g., mono- and diglycerides of fatty acids, skim milk powder, hexoses, pentoses, disaccharides, e.g., sucrose corn syrup and the like.

Surface active agents includes emulsifying agents, e.g., fatty acids such as capric acid, caprylic acid, palmitic acid, myristic acid and the like, mono- and diglycerides of fatty acids, lecithin, defoaming and flavor-dispersing agents such as sorbitan monostearate, potassium stearate, hydrogenated tallow alcohol and the like.

Conditioners include compounds such as bleaching and maturing agents, e.g., benzoyl peroxide, calcium peroxide, hydrogen peroxide and the like; starch modifiers such as peracetic acid, sodium chlorite, sodium hypochlorite, propylene oxide, succinic anhydride and the like, buffers and neutralizing agents, e.g., sodium acetate, ammonium bicarbonate, ammonium phosphate, citric acid, lactic acid, vinegar the the like; colorants, e.g., carminic acid, cochineal, tumeric and curcuma and the like; firming agents such as aluminum sodium sulfate, calcium chloride and calcium gluconate; texturizers, anti-caking agents, e.g., aluminum calcium sulfate and tribasic calcium phosphate; enzymes; yeast foods, e.g., calcium lactate and calcium sulfate; nutrient supplements, e.g., iron salts such as ferric phosphate, ferrous gluconate and the like, riboflavin, vitamins, zinc sources such as zinc chloride, zinc sulfate and the like.

Other flavorants and flavor intensifiers include aldehydes, esters, natural oils, alcohols, sulfides, ketones, lactones, carboxylic acids and hydrocarbons such as heliotropin, terpinenol-4, benzaldehyde, anisaldehyde, phenyl acetaldehyde, benzyl formate, benzyl acetate, cis-3-hexenyl benzoate, methyl hexanoate, hexanal, eucalyptol, eugenol, acetaldehyde, ethyl acetate, ethyl butyrate, turpentine gum oil, limonene, gum camphor, isobornyl acetate, borneol, cinnamic aldehyde, cuminic aldehyde, furfural, methyl cinnamate, cassia oil, vanillin, maltol, parahydroxybenzyl acetate, dimethyl sulfide, alphaionone, acetic acid, isobutyl acetate, acetone, butyric acid, formic acid, valeric acid, amyl acetate, amyl butyrate, anethol, benzyl salicylate, diacetyl, dimethyl anthranilate, ethyl methylphenylglycidate, ethyl succinate, ethyl valerate, geraniol, cis-3-hexen-1-ol, 2-hexenyl acetate, 2-hexenyl butyrate, hexyl butyrate, 4-(p-hydroxyphenyl)-2-butanone, betaionone, isobutyl cinnamate, jasmine, lemon essential oil, methyl butyrate, methyl caproate, methyl disulfide, methyl p-naphthyl ketone, orris butter, rose absolute, terpenyl acetate, gamma-undecalactone, vanilla and alcohol.

The specific flavoring adjuvant selected for use may be either solid or liquid depending upon the desired physical form of the ultimate product, i.e., foodstuff, whether simulated or natural, and should, in any event, (i) be organoleptically compatible with the norbornane derivatives of our invention by not covering or spoiling the organoleptic properties (aroma and/or taste) thereof; (ii) be non-reactive with the norbornane derivatives of our invention and (iii) be capable of providing an environment in which the norbornane derivatives can be dispersed or admixed to provide a homogeneous medium. In addition, selection of one or more flavoring adjuvants, as well as the quantities thereof will depend upon the precise organoleptic character desired in the finished product. Thus, in the case of flavoring compositions, ingredient selection will vary in accordance with the foodstuff, chewing gum, medicinal product or toothpaste to which the flavor and/or aroma are to be imparted, modified, altered or enhanced. In contradistinction, in the preparation of solid products, e.g., simulated foodstuffs, ingredients capable of providing normally solid compositions should be selected such as various cellulose derivatives.

As will be appeciated by those skilled in the art, the amount of norbornane derivatives employed in a particular instance can vary over a relatively wide range, depending upon the desired organoleptic effects to be achieved. Thus, correspondingly, greater amounts would be necessary in those instances wherein the ultimate food composition to be flavored is relatively bland to the taste, whereas relatively minor quantities may suffice for purposes of enhancing the composition merely deficient in natural flavor or aroma. The primary requirement is that the amount selected to be effective, i.e., sufficient to alter, modify, or enhance the organoleptic characteristics of the parent composition, whether foodstuff per se, chewing gum, per se, medicinal product per se, toothpaste per se, or flavoring composition.

The use of insufficient quantities of norbornane derivatives will, of course, substantially vitiate any possibility of obtaining the desired results while excess quantities prove needlessly costly and, in extreme cases, may disrupt the flavor-aroma balance, thus proving self-defeating.

Accordingly, the terminology "effective amount" and "sufficient amount" is to be accorded a significance in the context of the present invention consistent with the obtention of desired flavoring effects.

Thus, and with respect to ultimate food compositions, chewing gum compositions, medicinal product compositions and toothpaste compositions, it is found that quantities of norbornane derivatives ranging from a small but effective amount, e.g., 0.01 parts per million up to about 100 parts per million based on total composition are suitable. Concentrations in excess of the maximum quantity stated are not normally recommended, since they fail to prove commensurate enhancement of organoleptic properties. In those instances, wherein the norbornane derivatives are added to the foodstuff as an integral component of a flavoring composition, it is, of course, essential that the total quantity of flavoring composition employed be sufficient to yield an effective norbornane derivative concentration in the foodstuff product.

Food flavoring compositions prepared in accordance with the present invention preferably contain the norbornane derivatives in concentrations ranging from about 0.01% up to about 15% by weight based on the total weight of the said flavoring composition.

The composition described herein can be prepaed according to conventional techniques well known as typified by cake batters and fruit drinks and can be formulated by merely admixing the involved ingredients within the proportions stated in a suitable blender to obtain the desired consistency, homogeneity of dispersion, etc. Alternatively, flavoring compositions in the form of particulate solids can be conveniently prepared by mixing the norbornane derivatives with, for example, gum arabic, gum tragacanth, carrageenan and the like, and thereafter spray-drying the resultant mixture whereby to obtain the particular solid product. Preprepared flavor mixes in powder form e.g., a fruit-flavored powder mix are obtained by mixing the dried solid components, e.g., starch, sugar and the like and norbornane derivatives in a dry blender until the requisite degree of uniformity is achieved.

An additional aspect of our invention provides an organoleptically improved smoking tobacco product and additives therefor, as well as methods of making the same which overcome problems heretofore encountered in which desired spicy, cooling, clove-like, cinnamon bark-like, sweet, fruity, berry-like, juicyfruit, woody, piney, blueberry, banana, green, herbaceous, strawberry-like, and dill flavor characteristics of natural tobacco (prior to smoking and, on smoking, in the mainstream and in the sidestream) as well as cooling effects, are created or enhanced or modified or augmented and may be readily controlled and maintained at the desired uniform level regardless of variations in the tobacco components of the blend.

This invention further provides improved tobacco additives and methods whereby various desirable natural aromatic tobacco flavoring characteristics with spicy, cooling, clove-like, cinnamon bark-life, sweet, fruity, berry-like, juicyfruit, woody, piney, blueberry, banana, green, herbaceous, strawberry-like and dill notes may be imparted to smoking tobacco products and may be readily varied and controlled to produce the desired uniform flavoring characteristics.

In carrying out this aspect of our invention, we add to smoking tobacco materials or a suitable substitute therefor (e.g., dried lettuce leaves) an aroma and flavor additive containing as an active ingredient one or more norbornane derivatives of our invention.

In addition to the norbornane derivatives of our invention other flavoring and aroma additives may be added to the smoking tobacco material or substitute therefor either separately or in mixture with the norbornane derivatives as follows:

II. Natural Oils

Celery seed oil;

Coffee extract;

Bergamot oil;

Cocoa extract;

Nutmeg oil; and

Origanum oil.

An aroma and flavoring concentrate containing one or more niobornane norbornane of our invention and, if desired, one or more of the above indicated additional flavoring additives may be added to the smoking tobacco material, to the filter or to the leaf or paper wrapper. The smoking tobacco material may be shredded, cured, cased and blended together material or reconstituted tobacco material or tobacco substitutes (e.g., lettuce leaves) or mixtures thereof. The proportions of flavoring additives may be varied in accordance with taste but insofar as enhancement or the imparting of spicy and/or cooling and/or clove-like and/or cinnamon bark-like and/or sweet and/or fruity and/or berry-like and/or juicyfruit and/or woody and/or piney and/or blueberry and/or banana and/or green and/or herbaceous and/or strawberry-like and/or dill notes, we have found that satisfactory results are obtained if the proportion by weight of the sum total of norbornane derivative(s) to smoking tobacco material is between 50 ppm and 1,500 ppm (0.015%--0.15%). We have further found that satisfactory results are obtained if the proportions by weight of the sum total of norbornane derivative used to flavoring material is between 1,500 and 15,000 ppm (0.15%-1.5%).

Any convenient method for incorporating the norbornane derivative(s) into the tobacco product may be employed. Thus, the norbornane derivative(s) taken alone or along with other flavoring additives may be dissolved in a suitable solvent such as ethanol, diethyl ether and/or volative organic solvents and the resulting solution may either be spread on the cured, cased and blended tobacco material or the tobacco material may be dipped into such solution. Under certain circumstances, a solution of the norbornane derivative(s) taken alone or taken further together with other flavoring additives as set forth above, may be applied by means of a suitable applicator such as a brush or roller on the paper or leaf wrapper for the smoking product, or it may be applied to the filter by either spraying, or dipping, or coating.

Furthermore, it will be apparent that only a portion of the tobacco or substitute therefor need be treated and the thus treated tobacco may be blended with other tobaccos before the ultimate tobacco product is formed. In such cases, the tobacco treated by have the norbornane derivative(s) in excess of the amounts or concentrations above indicated so that when blended with other tobaccos, the final product will have the percentage within the indicated range.

In accordance with one specific example of our invention an aged, cured and shredded domestic burley tobacco is sprayed with a 20% ethanol solution of the mixture of 1,3-and 3,5-dimethyl-2-norbornane carboxylic acid methyl esters having the structures: ##STR120## in an amount of mixture to provide tobacco composition containing 800 ppm by weight of the mixture of the two esters on a dry basis. Thereafter the alcohol is removed by evaporation and the tobacco is manufactured into cigarettes by the usual techniques. The cigarette when treated as indicated has a desired and pleasing aroma which is detectable in the mainstream and the sidestream when the cigarette is smoked. This aroma is described as being sweeter, more aromatic, more tobacco-like having sweet, spicy, cooling, woody and clove-like notes.

While our invention is particularly useful in the manufacture of smoking tobacco, such as cigarette tobacco, cigar tobacco and pipe tobacco, other tobacco products, formed from sheeted tobacco dust or fines may also be used. Likewise, the norbornane derivative(s) of our invention can be incorporated with materials such as filter tip materials (e.g. cellulose acetate filters wherein spicy, cooling, clove-like, cinnamon bark-like, sweet, fruity, berry-like, juicyfruit, woody, piney, blueberry, banana, green, herbaceous, stawberry-like and/or dill effects are desired), seam paste, packaging materials and the like which are used along with tobacco to form a product adapted for smoking. Furthermore, the norbornane derivative(s) can be added to certain tobacco substitutes of natural or synthetic origin (e.g., dried lettuce leaves) and, accordingly, by the term "tobacco" as used throughtout this specification is meant any composition intended for human consumption by smoking or otherwise, whether composed of tobacco plant parts or substitute materials or both.

The norbornane derivative(s) and one or more auxiliary perfume ingredients, including, for example, hydrocarbons, alcohols, ketones, aldehydes, nitriles, esters, lactones or cyclic esters, synthetic essential oils and natural essential oils, may be admixed so that the combined odors of the individual components produce a pleasant and desired fragrance, particularly and preferably in fruity, banana, creamy, camphoraceous, herbaceous, strawberry-like, raspberry-like, reseda body-like, sweet, spicy, woody, eucalyptol-like, tagett-like, rum/butterscotch, balsamic, green, and/or minty fragrances. Such perfume compositions usually contain (a) the main note or the "bouquet: or foundation stone of the composition; (b) modifiers which round off and accompany the main note; (c) fixatives which include odorous substances which lend a particular note to the perfume throughout all stages of evaporation and substances which retard evaporation; and (d) topnotes which are usually low boiling fresh-smelling materials.

In perfume compositions, it is the individual components which contribute to their particular olfactory characteristics, however the overall sensory effect of the perfume composition will be at least the sum total of the effects of each of the ingredients. Thus, one or more of the norbornane derivative(s) of our invention can be used to alter, modify or enhance the aroma characteristics of a perfume composition, for example by utilizing or moderating the olfactory reaction contributed by another ingredient in the composition.

The amount of norbornane derivative(s) of our invention which will be effective in perfume compositions as well as perfumed articles and colognes depends on many factors, including the other ingredients, their amounts and the effects which are desired. It has been found that perfume compositions containing as little as 0.01% of norbornane derivative(s) or even less (e.g., 0.005%) can be used to impart a fruity, banana, creamy, camphoraceous, strawberry-like, raspberry-like, reseda body-like, herbaceous, sweet, spicy, woody, eucalyptol-like, rum/butterscotch, balsamic, green, minty, borneol-like, tagett-like and/or medicinal odor with camphor, minty and calamnus-like nuances to soaps, detergents (including anionic, nonionic, cationic and zwitterionic solid or liquid detergents), cosmetics, fabric softeners, dryer-added fabric softener articles, fabric whiteners and optical brighteners or other products. The amount employed can range up to 70% of the fragrance components and will depend on considerations of cost, nature of the end product, the effect desired on the finished product and the particular fragrance sought.

The norbornane dervative(s) of our invention are useful (taken alone or together with other ingredients in perfume compositions) in detergents and soaps, space odorants and deodorants, perfumes, colognes, toilet water, bath preparations, such as lacquers, brilliantines, pomades and shampoos; cosmetic preparations, such as creams, deodorants, hand lotions and sun screens; powders such as talcs, dusting powders, face powders and the like. As little of 0.005% of the norbornane derivative(s) (in the ultimate perfumed article) will suffice to impart an intense, fuity, banana, creamy, camphoraceous, strawberry-like, raspberry-like, reseda body-like, herbaceous, sweet, spicy, woody, eucalyptol-like, rum/butterscotch, balsamic, green, mintyl, borneol-like, tagett-like and/or medicinal note to various types of perfumed articles. Generally no more than 3% of the norbornane derivative(s) based on the ultimate end product (perfumed article) is required.

In addition, the perfume composition or fragrance composition of our invention can contain a vehicle, or carrier for the norbornane derivative(s). The vehicle can be a liquid such as a non-toxic alcohol, a non-toxic glycol or the like. The carrier can also be an absorbent solid, such as a gum (e.g., gum arabic), or components for encapsulating the composition (such as gelatin).

It will thus be apparent that the norbornane derivative(s) of our invention can be utilized to alter, modify or enhance sensory properties, particularly organoleptic properties such as flavor(s) and/or fragrance(s) of a wide variety of consumable materials.

The following examples serve to illustrate processes for specifically producing the norbornane derivative(s) useful in our invention.

The following examples also serve to illustrate specific embodiments of our invention.

It will be understood that these examples are illustrative and the invention is to be considered to be restricted thereto only as indicated in the appended claims.

All parts and percentages given herein are by weight unless otherwise specified.

EXAMPLE I Preparation of 1,3-Dimethyl-5-Norbornene-2-Carboxylic Acid Methyl Ester and 3,5-Dimethyl-5-Norbornene-2-Carboxylic Acid Methyl Ester (Catalytic Diels-Alder Reaction) ##STR121##

Into a 3 liter flask equipped with stirrer, thermometer, condenser, addition funnel and cooling bath are charged 1000 ml toluene, 500 grams methyl crotonate, 45 grams ethyl aluminum dichloride. The resulting mixture is cooled to 20°-25° C. Over a period of 50 minutes while maintaining the reaction mass at 24°-25° C., 320 grams of methyl cyclopentadiene (mixture of 1-methyl-1,3-cyclopentadiene and 2-methyl-1,3-cyclopentadiene (50% in toluene solution)) is added.

Two or three bottle capfuls of the above lotion held under the tap releasing the water into the bathtub yields a copiously foamed bubble bath with no visible precipitation flocculation, or "bathtub ring" even using hard water. Bathing in this bath is found to have a cleansing and pleasing emollient effect on the skin as described above.

When, after immersion in this bath, the body is soaped, rinsed and dried, an even better, more long-lasting emollient, moisturizing effect on the skin is observed. The foam or bubbles are substantially unaffected by the soaping step, and no precipitate, flocculate or "bathtub ring", or any bothersome film or coating on the bathtub surface is found.

The aroma produced is as is set forth in Table III below:

A shampoo of the above composition is made in the following matter. First, the tridecyloxy polyethoxy ethanol is added to a clean mixing tank, with the agitator on, and the amine oxide, polyoxyethylene sorbitan monolaurate and cocomonoethanolamine are added sequentially, with continued agitation. The mix is then heated to 68° C., until the cocomonoethanolamide is melted and/or dissolved. The hydrogen peroxide solution is then admixed with the mentioned nonionics and mixing is continued for about half an hour, in which the peroxide destroys any free amines or other harmful impurities that may be present. The mix is then cooled to 38° C.

In a separate mixer the polyacrylamide is gradually added to the formula weight of deionized water, with the mixer on. Addition is effected carefully and slowly (the polyacrylamide is sprinkled in) to avoid the production of "fish eyes" in the mix. After dissolving of the polyacrylamide the solution thereof is added to the first mixing tank with agitation and is blended with the nonionics, such mixings being at room temperature. Subsequently the perfume as indicated in Table V (below) giving rise to the aroma profile as set forth in Table V (below) is admixed with the balance of the composition and mixing is continued for another half hour.

The product made is an excellent shampoo of satisfactory viscosity and aroma, foaming power, foam stability, low conductivity and good shampooing effects. The viscosity is about 1,000 centipoises at 20° C. and the conductivity, using the Hach Conductivity Meter, is 750 micromhos/cm. The foaming power is 250 ml and the foam stability is 22 seconds, by the test method previously described. In comparison, a commercial shampoo based on triethanolamine lauryl sulphate detergent has a conductivity of about 22,000 micromhos/cm, a viscosity of about 1,500 centipoises, a foaming power of about 380 ml and a foam stability of 60 seconds.

In panel evaluations of the experimental shampoo compared to a different commercial product, in actual shampooing, the experimental formula was adjudged significantly better in being less drying, porducing a softer feel for the wet hair, leaving the wet hair easier to comb, being less prone to accumulate static charges (less flyaway) and having a foam of better appearance and feel. Additionally, the experimental product was judged better in almost all hair effect properties, with the control only being about equal to it in curl retention. In properties other than those mentioned the experimental product was better in rinsability, the control was better in foam build-up rate and the foams were about equal in volume and stability.

In the shampooing described herein and in subsequent Examples the human hair is washed on the head by wetting the hair with warm tap water at about 42° C., applying 15 grams of shampoo to the hair, lathering it into the hair for a minute, rinsing with warm tap water for 30 seconds, re-lathering with 7 grams of shampoo for a minute and rinsing off for 30 seconds, after which the hair is towel dried and dried further with an automatic hair dryer.

EXAMPLE XIV Fabric Freshener Composition

A fabric freshener composition is prepared as follows:

The composition of this Example is prepared by simply mixing the ingredients.

The above described composition is applied to a lightly soiled and wrinkled fabric as droplets (ca. 5.0 mm avg. size) using a trigger acton sprayer having a nozzle which is adjustable to provide composition droplets in the desired range. The composition is applied at a rate of about 1 gram of composition to about 10 grams of fabric.

The fabric is then placed in an automatic dryer and dried, with tumbling action, at a temperature of 60° C.-80° C. for a period of 15 minutes. The fabric is rendered free of wrinkles and static, and has a fresh appearance and pleasant odor profile as set forth in Table VI below. Surprisingly, the sodium bicarbonate is not visible on the refreshed fabric.

In the foregoing procedure, substantially the same results were obtained when sodium carbonate is substituted for the sodium bicarbonate.

The above formulation is split into 5 portions. To the first four portions are added at the rate of 1%, the norbornane derivatives of Table IX. To the fifth portion nothing is added. All five formulations with and without said norbornyl derivatives are combined with water at the rate of 100 ppm. The flavor of the first four portions each including a norbornyl derivative prepared according to the preceeding examples as indicated in Table IX below have fruity, blueberry characteristics with several other nuances as indicated in Table IX below and are all closely similar to the flavor of wild blueberries. It is therefore preferred to use the formulations containing the norbornyl derivatives as listed in Table IX below, to the basic blueberry formulation which does not contain any of said norbornyl derivatives.

The above formulation is split into five parts. Two the first four parts, at the rate of 0.3% are added the norbornyl derivative produced according to the preceeding examples, as set forth in Table X below. No additive is added to the fifth part. The five formulations are compared in water at the rate of 50 ppm. The four flavors containing the norbornyl derivatives have more ripe raspberry tastes and woody, raspberry kernel characters. They also have additional nuances as set forth in Table X below. Therefore the raspberry formulations containing the four norbornyl derivatives as additives have more natural-like and more characteristic raspberry flavors and are therefore preferred.

The control cigarettes not containing the norbornyl derivatives as set forth in Table XI and the experimental cigarettes which contain the norbornyl derivatives as set forth in Table XI are evaluated by paired comparison and the results are as follows:

The experimental cigarettes, are found, on smoking, to have a sweeter, spicy, woody-oriental, clove-like taste with much more body and much more natural tobacco-like aroma prior to smoking and on smoking in the mainstream and the sidestream. The experimental cigarettes containing the product produced according to Example II in addition have cooling nuances. The experimental cigarettes produced containing the product produced according to Example III also have cinnamon bark nuances prior to and on smoking in the mainstream and in the sidestream.

All cigarettes are evaluated for smoke flavor with a 20 mm cellulose acetate filter.

Accordingly, it is concluded that the norbornyl derivatives set forth in Table XI produced according to the processes of Examples II and III enhance the tobacco-like taste and aroma particularly the oriental-like taste of the blended cigarette imparting to it sweet, spicy and woody-oriental tobacco-like nuances and in addition clove-like nuances.

EXAMPLE XXIX

The following is a description of a preferred embodiment of the invention as carried out using a process wherein minute capsules having a diameter in the range of 50 up to 500 microns were added to a wet web of reconstituted tobacco (weight ratio of dry web to dry capsules=1:0.04. The capsules and binder materials (weight ratio of dry capsule to dry binder=1:0.1 when placed among the tobacco fibers, wet them and entangle with them and clothe them, thus in effect securing and binding the capsules against migration through the sheet, thereby forming a subsident stratum. The majority of binder and associated capsules are caught in the sheet. Substantially no capsules migrate through the sheet. When the wet tobacco web is dried, the binder shrinks by loss of solvent, leaving the dried polymeric binder material, and the capsules remain in place relatively with respect to sheet thickness. The sheets containing the capsules are then shredded and used in producing smoking articles such as cigarettes. Such cigarettes are formed using a wrapper, containing a fill of tobacco extending from one end of the wrapper to the other, and intimately admixed with the tobacco, a plurality of microcapsules each comprising an aromatic volatile synthetic clove oil flavorant. The capsules are homogeneously spaced in contiguous relationship with the tobacco such that as the burning front of the tobacco advances the length of the tobacco article, a concomitant elevation of temperature initiates consecutive rupture of the capsules (1) releasing the volatile synthetic clove oil-containing material which emanates with smoke from the smoking article into the smoker's mouth and (2) yielding a crackling sound audible to the human ear.

Tragacanth gum solution and starch solution were prepared in the following manner:

PART A Concentrated Tragacanth Gum Solution (Binder)

4.5 Pounds of dry tragacanth gum powder were stirred into 50 gallons of water, using a suitable mixer. Five minutes after all the powder had been added, the mixer was turned off. The tragacanth gum solution was allowed to stir for 2 hours, and then the mixer was turned on for 5 minutes. Sitting for 2 additional hours, enabled the tragacanth gum to hydrate. After five minutes, the mixer was turned off, and the 55 gallon drum was covered. Just prior to combining the tragacanth gum solution and the capsular slurry, 50 gallons of tragacanth gum solution was diluted with water to 3 percent tragacanth gum on a solids basis.

PART B Starch Solution

The hydrolyzed starch solution was prepared by heating a slurry of the starch at 190 degrees Fahrenheit for a minimum of 15 minutes to provide a 1 percent by weight, starch-in-water solution.

Capsule slurries were prepared in the following manner:

PART D Preparation of Capsular Slurry-Encapsulation of Synthetic Clove Oil

Ten grams of gum arabic were dissolved at room temperature in 220 grams of deionized water. The mixture was agitated until the gum arabic was fully dissolved. In a separate 240 milliliter Erlenmeyer flask, 10.0 grams of modified gelatin was mixed with 220.0 grams of deionized water. The gelatin was allowed to tumefy at room temperature and also then warmed in a water bath to about 40° C. With stirring so that the gelatin was dissolved.

The gelatin solution and the gum arabic solution were poured into a beaker equipped with a stirrer. A flocculence indicating the precipitation of the gelatin was noted. The temperature of the mixture was decreased to 35° C. The speed of the stirrer was adjusted so that it was turning only enough to keep the phases mixed. The pH of the mixture was 4.50.

Into the beaker containing the mixture of gum arabic and gelatin was poured 118.0 grams of synthetic clove oil as prepared in Part C. The speed of the stirrer was then adjusted to mix the colloids and the oil. The oil separated into droplets. Two drops of octyl alcohol were added to prevent foaming. The progress of the coacervation was monitored by means of microscopic examination.

The temperature of the mixture was lowered to room temperature, e.g., 24° C. At the higher temperature of 31° C., colloid deposition was observed on the oil droplets. At 24° C., little colloid could be observed in aqueous portions of the mixture. Deposition had ceased. Stirring was continued for 30 minutes, whereupon the reaction mixture was cooled on an ice bath to 4° C. The reaction mixture was maintained at this temperature for 200 minutes. (When hardening was desired, 1.0 milliliters of a 25 percent glutaraldehyde in water per gram of gelatin is added.)

The internal phase of the capsules thus formed was approximately 80-90 percent of the total weight of the capsules.

The capsules thus produced had diameters in the range of from 50 up to 500 microns. They were coated with the binder onto a tobacco sheet material which was shredded and used as a fill in the manufacture of a smoking article.

PART E Variation of the Encapsulation of Synthetic Clove Oil

A variation of the encapsulation procedure set forth immediately supra is shown below.

The solution of gum arabic was warmed to 38° C., placed in a Waring blender and stirred. The clove oil prepared in Part C was added gradually while the speed of the blender was being increased until the size of the clove oil droplets was approximately 50-500 microns. The mixture thus formed was poured into a 1,000 milliliter beaker containing gelatin, also at 38° C., and was stirred thoroughly. The temperature was then allowed to drop to room temperature and then further decreased to a temperature of 4° C. to 10° C. by means of an ice bath.

It is evident that the tobacco film or filaments can be made from various types and combinations of tobacco. For instance, the tobacco sheet material can be made from relatively expensive tobacco such as Latakia in which it is highly desirous to use all waste because of the high price thereof. So, also, it may be formed of Burley or one or more scrap or waste cigarette type tobaccos and incorporated in accordance with a particular cigarette manufacture's formula as if it were natural cigarette tobacco leaves. Any desired formula can thus be maintained in accordance with the demands of a manufacturer's particular brand using one or more types of natural shredded tobacco leaves and admixed desired quantities of shredded capsule containing tobacco film material or filaments, either as a blending or flavoring medium or both or for purposes of bulking.

In the case of the manufacture of cigarettes, according to the present invention, tobacco films are shredded into strands or the film is formed directly into filaments substantially the width of the strands of natural shredded tobacco and of any desired length. In the case of cigars, the capsule containing films are used in large pieces much as long filler tobacco and forming long filler cigars. In all cases the shredded film or filaments or film used in cigarettes and cigars can be handled either manually or by machine in the same manner as natural shredded tobacco leaves or whole leaves or portions thereof. The amount of shredded capsule-containing reconstituted tobacco or pieces of this material employed in a particular blend in cigarettes or cigars, respectively, will vary according to types of tobacco used in the sheet material and the requirements oa a particular manufacture.
